This 20W solar panel is ideal for running small 12VDC loads such as electric fences, data loggers and monitoring equipment. It can also be used to trickle-charge 12V batteries, keeping them in top shape when stored. Expect about 2 hours of full production in winter in Canada – roughly 1.2Ahr/day. In summer this increases to 3Ahr/day. It can be directly connected to larger batteries, or through a charge controller for small sealed battery systems. The ideal mounting angle for maximum winter production is 70 degrees. Mates with SPM-20 solar mount (extra).
